Abstract: A touch panel device includes a touch panel and two or more controllers. The touch panel includes four regions. Each region includes a plurality of driving conductors extended along a first direction, and a plurality of sensing conductors extended along a second direction perpendicular to the first direction. Each controller is in charge of one of the region. Since the length of each driving conductor and each sensing conductors is one half of that of the conventional driving conductor and sensing conductor, each controller controls one fourth of the area of the touch panel, and is responsible for one fourth of the capacitance of the touch panel. The touch panel device can be well controlled by the controller without using a single controller with higher detecting sensibility and cost.

Abstract: A sensing device placed in a touch sensing system of a display device includes a selector, a sensing module, and a detection module for determining touch signals generated by the touch sensing system. The selector selects two of the touch signals according to at least one selection control signal. The sensing module comprises a first differential amplifier for comparing the selected touch signals and producing a first differential signal according to first control signals. According to second control signals, the detection module receives the first differential signal, generates an averaged sensing value and a reference value, and compares the averaged sensing value with the reference value to produce a second differential signal. Thereby, the touch sensing system uses the second differential signal to generate the first control signals and the second control signals to control the operation of the touch sensing system.

Abstract: An electronic device includes a touch panel, a driving circuit, and a sensing circuit. The driving circuit generates a driving signal, and superposes phase information on the driving signal. The touch panel includes multiple crossing conductors, for providing a sensing signal in response to a contact of an object on one of the sensing conductors and to a driving signal applied on the sensing element. The sensing circuit includes a signal extractor and a tag detector. The signal extractor generates a demodulation signal based on the period of the driving signal, width of the phase information, and for demodulating the sensing signal by using the demodulation signal to determine a sensing value. The tag detector enables the signal extractor as soon as a magnitude of the sensing signal is over a predetermined threshold. The signal demodulates the sensing signal by using a demodulation signal whose period is the same as the driving signal to determine the sensing value. The present electronic device can determine a touch position by processing of analog signal using the demodulation signal without phase compensation.
